• How To Install Docker on Linux Mint 20

  In this tutorial, we will show you how to install Docker on Linux Mint 20. For those of you who didn’t know, Docker is an open-source project that automates the deployment of the application inside the software container. The container allows the developer to package up all project resources such as libraries, dependencies, assets, etc. Docker is written in a Go Programming language and is developed by Dot cloud. It is basically a container engine that uses the Linux Kernel features like namespaces and control groups to create containers on top of an operating system and automates the application deployment on the container. This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo‘ to the commands to get root privileges. I will show you through the step by step installation of Docker on a Linux Mint 20 (Ulyana).

• How to Secure Email Server Against Hacking with VPN (CentOS/RHEL)

  In this tutorial, I’m going to share with you my tips and tricks to secure CentOS/RHEL email servers against hacking with a self-hosted VPN server. Many spammers are trying to hack into other people’s email servers. If successful, they would use the hacked email server to send large volumes of spam or steal valuable data. Why do we use a self-hosted VPN server? Because it allows you to enable whitelisting, so only trusted users connected to the VPN server can access your mail server.

• Fixed compile of libvdpau-va-gl in OE

  I posted yesterday about the problem in OpenEmbedded when the compile of a package requires execution of a binary: https://bkhome.org/news/202101/fixed-compile-of-samba-without-krb5-in-oe.html This problem does not occur if the build-architecture and target-architectures are the same. The problem occurs with a cross-compile. Today I had the same problem, with package 'libvdpau-va-gl'. I had previously compiled this in OE, but now the build-arch is x86_64 and the target-arch is aarch64.

KDE: Kate and Konsole

 

• The Kate Text Editor - January 2021

  It not only got some nice visual refresh but a much better fuzzy matching algorithm. The fuzzy matching algorithm is on its way to be upstream to KCoreAddons to be used by more parts of the KDE universe. Praise to Waqar Ahmed for implementing this and pushing it to upstream. And thanks to Forrest Smith for allowing us to use his matching algorithm under LGPLv2+! [...] As you can see on our team page a lot of new people helped out in the scope of the last year. I hope to see more people showing up there as new contributors. It is a pleasure that Waqar Ahmed & Jan Paul Batrina now have full KDE developer accounts! Especially Waqar came up with a lot of nifty ideas what could be fixed/improved/added and he did already do a lot of work to actually get these things done! I actually wanted to write earlier about what cool new stuff is there, but had too much review requests to look after. Great! ;=) No I can read review request instead of light novels in the evening.

 

• Contributing to Konsole

  I never thought I could contribute with Open Source, or even imagined I could change my workspace, in my mind doing it was beyond my programming skills. I was a Windows user for a long time, until one day I couldn’t stand anymore how the system was so slow, it was not a top computer, but it was a reasonable one to be that slow. So I changed to Debian and used it for a time until change to other distros, but I was amazed how fast it was, of course I couldn’t use all of the same programs I used to work with but I did learn new ones.
